This patch updates Kconfig to a more recent version of Kconfig, found
in Linux v5.4.0, 219d54332a09 ("Linux 5.4").
With the updated version of Kconfig, other changes are necessary to
avoid breaking the build.
Kconfig files:
- fix Kconfig files that where using option env=*:
Since Linux commit 104daea149c4 ("kconfig: reference environment
variables directly and remove 'option env='"), we can access the
environment directly via $() and "option env=" as been removed.
- CONFIG_EXPERT='y' will now appear in .config file if
XEN_CONFIG_EXPERT=y in the environment. The alternative is to change
"EXPERT" to "$(XEN_CONFIG_EXPERT)" in all Kconfig files.
Makefile:
- silentoldconfig target as been removed from Kconfig. To update
include/generated/autoconf.h, we need to use syncconfig target
instead.
Makefile.kconfig:
- Import newer needed code from Linux's Makefile.lib and
Kbuild.include and Makefile.build.
- Set Q to empty, Xen build system doesn't silence commands. Having Q
empty mean we can import stuff from Linux without having to remove the
leading $(Q) from build commands. And quiet='' means commands will be
echoed.
- Add $(PHONY) to .PHONY. Like it is intended by Kbuild.
Makefile.host is also updated and copied from Linux.
Dependency change:
- Now depends on flex/bison, maybe we could _shipped those files like
before. Linux doesn't do that anymore.
The .gitignore in kconfig/ has more entries, compared to upstream, for
file generated by Makefile.host.

Notes:
v2:
- Moved *.lex.c *.tab.[ch] back to kconfig/, and updated patch
description describing why it's different from upstream.

+================
+Kconfig Language
+================
+
+Introduction
+------------
+
+The configuration database is a collection of configuration options
+organized in a tree structure::
+
+ +- Code maturity level options
+ | +- Prompt for development and/or incomplete code/drivers
+ +- General setup
+ | +- Networking support
+ | +- System V IPC
+ | +- BSD Process Accounting
+ | +- Sysctl support
+ +- Loadable module support
+ | +- Enable loadable module support
+ | +- Set version information on all module symbols
+ | +- Kernel module loader
+ +- ...
+
+Every entry has its own dependencies. These dependencies are used
+to determine the visibility of an entry. Any child entry is only
+visible if its parent entry is also visible.
+
+Menu entries
+------------
+
+Most entries define a config option; all other entries help to organize
+them. A single configuration option is defined like this::
+
+ config MODVERSIONS
+ bool "Set version information on all module symbols"
+ depends on MODULES
+ help
+ Usually, modules have to be recompiled whenever you switch to a new
+ kernel. ...
+
+Every line starts with a key word and can be followed by multiple
+arguments. "config" starts a new config entry. The following lines
+define attributes for this config option. Attributes can be the type of
+the config option, input prompt, dependencies, help text and default
+values. A config option can be defined multiple times with the same
+name, but every definition can have only a single input prompt and the
+type must not conflict.
+
+Menu attributes
+---------------
+
+A menu entry can have a number of attributes. Not all of them are
+applicable everywhere (see syntax).
+
+- type definition: "bool"/"tristate"/"string"/"hex"/"int"
+
+ Every config option must have a type. There are only two basic types:
+ tristate and string; the other types are based on these two. The type
+ definition optionally accepts an input prompt, so these two examples
+ are equivalent::
+
+ bool "Networking support"
+
+ and::
+
+ bool
+ prompt "Networking support"
+
+- input prompt: "prompt" <prompt> ["if" <expr>]
+
+ Every menu entry can have at most one prompt, which is used to display
+ to the user. Optionally dependencies only for this prompt can be added
+ with "if".
+
+- default value: "default" <expr> ["if" <expr>]
+
+ A config option can have any number of default values. If multiple
+ default values are visible, only the first defined one is active.
+ Default values are not limited to the menu entry where they are
+ defined. This means the default can be defined somewhere else or be
+ overridden by an earlier definition.
+ The default value is only assigned to the config symbol if no other
+ value was set by the user (via the input prompt above). If an input
+ prompt is visible the default value is presented to the user and can
+ be overridden by him.
+ Optionally, dependencies only for this default value can be added with
+ "if".
+
+ The default value deliberately defaults to 'n' in order to avoid bloating the
+ build. With few exceptions, new config options should not change this. The
+ intent is for "make oldconfig" to add as little as possible to the config from
+ release to release.
+
+ Note:
+ Things that merit "default y/m" include:
+
+ a) A new Kconfig option for something that used to always be built
+ should be "default y".
+
+ b) A new gatekeeping Kconfig option that hides/shows other Kconfig
+ options (but does not generate any code of its own), should be
+ "default y" so people will see those other options.
+
+ c) Sub-driver behavior or similar options for a driver that is
+ "default n". This allows you to provide sane defaults.
+
+ d) Hardware or infrastructure that everybody expects, such as CONFIG_NET
+ or CONFIG_BLOCK. These are rare exceptions.
+
+- type definition + default value::
+
+ "def_bool"/"def_tristate" <expr> ["if" <expr>]
+
+ This is a shorthand notation for a type definition plus a value.
+ Optionally dependencies for this default value can be added with "if".
+
+- dependencies: "depends on" <expr>
+
+ This defines a dependency for this menu entry. If multiple
+ dependencies are defined, they are connected with '&&'. Dependencies
+ are applied to all other options within this menu entry (which also
+ accept an "if" expression), so these two examples are equivalent::
+
+ bool "foo" if BAR
+ default y if BAR
+
+ and::
+
+ depends on BAR
+ bool "foo"
+ default y
+
+- reverse dependencies: "select" <symbol> ["if" <expr>]
+
+ While normal dependencies reduce the upper limit of a symbol (see
+ below), reverse dependencies can be used to force a lower limit of
+ another symbol. The value of the current menu symbol is used as the
+ minimal value <symbol> can be set to. If <symbol> is selected multiple
+ times, the limit is set to the largest selection.
+ Reverse dependencies can only be used with boolean or tristate
+ symbols.
+
+ Note:
+ select should be used with care. select will force
+ a symbol to a value without visiting the dependencies.
+ By abusing select you are able to select a symbol FOO even
+ if FOO depends on BAR that is not set.
+ In general use select only for non-visible symbols
+ (no prompts anywhere) and for symbols with no dependencies.
+ That will limit the usefulness but on the other hand avoid
+ the illegal configurations all over.
+
+- weak reverse dependencies: "imply" <symbol> ["if" <expr>]
+
+ This is similar to "select" as it enforces a lower limit on another
+ symbol except that the "implied" symbol's value may still be set to n
+ from a direct dependency or with a visible prompt.
+
+ Given the following example::
+
+ config FOO
+ tristate
+ imply BAZ
+
+ config BAZ
+ tristate
+ depends on BAR
+
+ The following values are possible:
+
+ === === ============= ==============
+ FOO BAR BAZ's default choice for BAZ
+ === === ============= ==============
+ n y n N/m/y
+ m y m M/y/n
+ y y y Y/n
+ y n * N
+ === === ============= ==============
+
+ This is useful e.g. with multiple drivers that want to indicate their
+ ability to hook into a secondary subsystem while allowing the user to
+ configure that subsystem out without also having to unset these drivers.
+
+- limiting menu display: "visible if" <expr>
+
+ This attribute is only applicable to menu blocks, if the condition is
+ false, the menu block is not displayed to the user (the symbols
+ contained there can still be selected by other symbols, though). It is
+ similar to a conditional "prompt" attribute for individual menu
+ entries. Default value of "visible" is true.
+
+- numerical ranges: "range" <symbol> <symbol> ["if" <expr>]
+
+ This allows to limit the range of possible input values for int
+ and hex symbols. The user can only input a value which is larger than
+ or equal to the first symbol and smaller than or equal to the second
+ symbol.
+
+- help text: "help" or "---help---"
+
+ This defines a help text. The end of the help text is determined by
+ the indentation level, this means it ends at the first line which has
+ a smaller indentation than the first line of the help text.
+ "---help---" and "help" do not differ in behaviour, "---help---" is
+ used to help visually separate configuration logic from help within
+ the file as an aid to developers.
+
+- misc options: "option" <symbol>[=<value>]
+
+ Various less common options can be defined via this option syntax,
+ which can modify the behaviour of the menu entry and its config
+ symbol. These options are currently possible:
+
+ - "defconfig_list"
+ This declares a list of default entries which can be used when
+ looking for the default configuration (which is used when the main
+ .config doesn't exists yet.)
+
+ - "modules"
+ This declares the symbol to be used as the MODULES symbol, which
+ enables the third modular state for all config symbols.
+ At most one symbol may have the "modules" option set.
+
+ - "allnoconfig_y"
+ This declares the symbol as one that should have the value y when
+ using "allnoconfig". Used for symbols that hide other symbols.
+
+Menu dependencies
+-----------------
+
+Dependencies define the visibility of a menu entry and can also reduce
+the input range of tristate symbols. The tristate logic used in the
+expressions uses one more state than normal boolean logic to express the
+module state. Dependency expressions have the following syntax::
+
+ <expr> ::= <symbol> (1)
+ <symbol> '=' <symbol> (2)
+ <symbol> '!=' <symbol> (3)
+ <symbol1> '<' <symbol2> (4)
+ <symbol1> '>' <symbol2> (4)
+ <symbol1> '<=' <symbol2> (4)
+ <symbol1> '>=' <symbol2> (4)
+ '(' <expr> ')' (5)
+ '!' <expr> (6)
+ <expr> '&&' <expr> (7)
+ <expr> '||' <expr> (8)
+
+Expressions are listed in decreasing order of precedence.
+
+(1) Convert the symbol into an expression. Boolean and tristate symbols
+ are simply converted into the respective expression values. All
+ other symbol types result in 'n'.
+(2) If the values of both symbols are equal, it returns 'y',
+ otherwise 'n'.
+(3) If the values of both symbols are equal, it returns 'n',
+ otherwise 'y'.
+(4) If value of <symbol1> is respectively lower, greater, lower-or-equal,
+ or greater-or-equal than value of <symbol2>, it returns 'y',
+ otherwise 'n'.
+(5) Returns the value of the expression. Used to override precedence.
+(6) Returns the result of (2-/expr/).
+(7) Returns the result of min(/expr/, /expr/).
+(8) Returns the result of max(/expr/, /expr/).
+
+An expression can have a value of 'n', 'm' or 'y' (or 0, 1, 2
+respectively for calculations). A menu entry becomes visible when its
+expression evaluates to 'm' or 'y'.
+
+There are two types of symbols: constant and non-constant symbols.
+Non-constant symbols are the most common ones and are defined with the
+'config' statement. Non-constant symbols consist entirely of alphanumeric
+characters or underscores.
+Constant symbols are only part of expressions. Constant symbols are
+always surrounded by single or double quotes. Within the quote, any
+other character is allowed and the quotes can be escaped using '\'.
+
+Menu structure
+--------------
+
+The position of a menu entry in the tree is determined in two ways. First
+it can be specified explicitly::
+
+ menu "Network device support"
+ depends on NET
+
+ config NETDEVICES
+ ...
+
+ endmenu
+
+All entries within the "menu" ... "endmenu" block become a submenu of
+"Network device support". All subentries inherit the dependencies from
+the menu entry, e.g. this means the dependency "NET" is added to the
+dependency list of the config option NETDEVICES.
+
+The other way to generate the menu structure is done by analyzing the
+dependencies. If a menu entry somehow depends on the previous entry, it
+can be made a submenu of it. First, the previous (parent) symbol must
+be part of the dependency list and then one of these two conditions
+must be true:
+
+- the child entry must become invisible, if the parent is set to 'n'
+- the child entry must only be visible, if the parent is visible::
+
+ config MODULES
+ bool "Enable loadable module support"
+
+ config MODVERSIONS
+ bool "Set version information on all module symbols"
+ depends on MODULES
+
+ comment "module support disabled"
+ depends on !MODULES
+
+MODVERSIONS directly depends on MODULES, this means it's only visible if
+MODULES is different from 'n'. The comment on the other hand is only
+visible when MODULES is set to 'n'.
+
+
+Kconfig syntax
+--------------
+
+The configuration file describes a series of menu entries, where every
+line starts with a keyword (except help texts). The following keywords
+end a menu entry:
+
+- config
+- menuconfig
+- choice/endchoice
+- comment
+- menu/endmenu
+- if/endif
+- source
+
+The first five also start the definition of a menu entry.
+
+config::
+
+ "config" <symbol>
+ <config options>
+
+This defines a config symbol <symbol> and accepts any of above
+attributes as options.
+
+menuconfig::
+
+ "menuconfig" <symbol>
+ <config options>
+
+This is similar to the simple config entry above, but it also gives a
+hint to front ends, that all suboptions should be displayed as a
+separate list of options. To make sure all the suboptions will really
+show up under the menuconfig entry and not outside of it, every item
+from the <config options> list must depend on the menuconfig symbol.
+In practice, this is achieved by using one of the next two constructs::
+
+ (1):
+ menuconfig M
+ if M
+ config C1
+ config C2
+ endif
+
+ (2):
+ menuconfig M
+ config C1
+ depends on M
+ config C2
+ depends on M
+
+In the following examples (3) and (4), C1 and C2 still have the M
+dependency, but will not appear under menuconfig M anymore, because
+of C0, which doesn't depend on M::
+
+ (3):
+ menuconfig M
+ config C0
+ if M
+ config C1
+ config C2
+ endif
+
+ (4):
+ menuconfig M
+ config C0
+ config C1
+ depends on M
+ config C2
+ depends on M
+
+choices::
+
+ "choice" [symbol]
+ <choice options>
+ <choice block>
+ "endchoice"
+
+This defines a choice group and accepts any of the above attributes as
+options. A choice can only be of type bool or tristate. If no type is
+specified for a choice, its type will be determined by the type of
+the first choice element in the group or remain unknown if none of the
+choice elements have a type specified, as well.
+
+While a boolean choice only allows a single config entry to be
+selected, a tristate choice also allows any number of config entries
+to be set to 'm'. This can be used if multiple drivers for a single
+hardware exists and only a single driver can be compiled/loaded into
+the kernel, but all drivers can be compiled as modules.
+
+A choice accepts another option "optional", which allows to set the
+choice to 'n' and no entry needs to be selected.
+If no [symbol] is associated with a choice, then you can not have multiple
+definitions of that choice. If a [symbol] is associated to the choice,
+then you may define the same choice (i.e. with the same entries) in another
+place.
+
+comment::
+
+ "comment" <prompt>
+ <comment options>
+
+This defines a comment which is displayed to the user during the
+configuration process and is also echoed to the output files. The only
+possible options are dependencies.
+
+menu::
+
+ "menu" <prompt>
+ <menu options>
+ <menu block>
+ "endmenu"
+
+This defines a menu block, see "Menu structure" above for more
+information. The only possible options are dependencies and "visible"
+attributes.
+
+if::
+
+ "if" <expr>
+ <if block>
+ "endif"
+
+This defines an if block. The dependency expression <expr> is appended
+to all enclosed menu entries.
+
+source::
+
+ "source" <prompt>
+
+This reads the specified configuration file. This file is always parsed.
+
+mainmenu::
+
+ "mainmenu" <prompt>
+
+This sets the config program's title bar if the config program chooses
+to use it. It should be placed at the top of the configuration, before any
+other statement.
+
+'#' Kconfig source file comment:
+
+An unquoted '#' character anywhere in a source file line indicates
+the beginning of a source file comment. The remainder of that line
+is a comment.
+
+
+Kconfig hints
+-------------
+This is a collection of Kconfig tips, most of which aren't obvious at
+first glance and most of which have become idioms in several Kconfig
+files.
+
+Adding common features and make the usage configurable
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+It is a common idiom to implement a feature/functionality that are
+relevant for some architectures but not all.
+The recommended way to do so is to use a config variable named HAVE_*
+that is defined in a common Kconfig file and selected by the relevant
+architectures.
+An example is the generic IOMAP functionality.
+
+We would in lib/Kconfig see::
+
+ # Generic IOMAP is used to ...
+ config HAVE_GENERIC_IOMAP
+
+ config GENERIC_IOMAP
+ depends on HAVE_GENERIC_IOMAP && FOO
+
+And in lib/Makefile we would see::
+
+ obj-$(CONFIG_GENERIC_IOMAP) += iomap.o
+
+For each architecture using the generic IOMAP functionality we would see::
+
+ config X86
+ select ...
+ select HAVE_GENERIC_IOMAP
+ select ...
+
+Note: we use the existing config option and avoid creating a new
+config variable to select HAVE_GENERIC_IOMAP.
+
+Note: the use of the internal config variable HAVE_GENERIC_IOMAP, it is
+introduced to overcome the limitation of select which will force a
+config option to 'y' no matter the dependencies.
+The dependencies are moved to the symbol GENERIC_IOMAP and we avoid the
+situation where select forces a symbol equals to 'y'.
+
+Adding features that need compiler support
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+There are several features that need compiler support. The recommended way
+to describe the dependency on the compiler feature is to use "depends on"
+followed by a test macro::
+
+ config STACKPROTECTOR
+ bool "Stack Protector buffer overflow detection"
+ depends on $(cc-option,-fstack-protector)
+ ...
+
+If you need to expose a compiler capability to makefiles and/or C source files,
+`CC_HAS_` is the recommended prefix for the config option::
+
+ config CC_HAS_STACKPROTECTOR_NONE
+ def_bool $(cc-option,-fno-stack-protector)
+
+Build as module only
+~~~~~~~~~~~~~~~~~~~~
+To restrict a component build to module-only, qualify its config symbol
+with "depends on m". E.g.::
+
+ config FOO
+ depends on BAR && m
+
+limits FOO to module (=m) or disabled (=n).
+
+Kconfig recursive dependency limitations
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you've hit the Kconfig error: "recursive dependency detected" you've run
+into a recursive dependency issue with Kconfig, a recursive dependency can be
+summarized as a circular dependency. The kconfig tools need to ensure that
+Kconfig files comply with specified configuration requirements. In order to do
+that kconfig must determine the values that are possible for all Kconfig
+symbols, this is currently not possible if there is a circular relation
+between two or more Kconfig symbols. For more details refer to the "Simple
+Kconfig recursive issue" subsection below. Kconfig does not do recursive
+dependency resolution; this has a few implications for Kconfig file writers.
+We'll first explain why this issues exists and then provide an example
+technical limitation which this brings upon Kconfig developers. Eager
+developers wishing to try to address this limitation should read the next
+subsections.
+
+Simple Kconfig recursive issue
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Read: Documentation/kbuild/Kconfig.recursion-issue-01
+
+Test with::
+
+ make KBUILD_KCONFIG=Documentation/kbuild/Kconfig.recursion-issue-01 allnoconfig
+
+Cumulative Kconfig recursive issue
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Read: Documentation/kbuild/Kconfig.recursion-issue-02
+
+Test with::
+
+ make KBUILD_KCONFIG=Documentation/kbuild/Kconfig.recursion-issue-02 allnoconfig
+
+Practical solutions to kconfig recursive issue
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Developers who run into the recursive Kconfig issue have two options
+at their disposal. We document them below and also provide a list of
+historical issues resolved through these different solutions.
+
+ a) Remove any superfluous "select FOO" or "depends on FOO"
+ b) Match dependency semantics:
+
+ b1) Swap all "select FOO" to "depends on FOO" or,
+
+ b2) Swap all "depends on FOO" to "select FOO"
+
+The resolution to a) can be tested with the sample Kconfig file
+Documentation/kbuild/Kconfig.recursion-issue-01 through the removal
+of the "select CORE" from CORE_BELL_A_ADVANCED as that is implicit already
+since CORE_BELL_A depends on CORE. At times it may not be possible to remove
+some dependency criteria, for such cases you can work with solution b).
+
+The two different resolutions for b) can be tested in the sample Kconfig file
+Documentation/kbuild/Kconfig.recursion-issue-02.
+
+Below is a list of examples of prior fixes for these types of recursive issues;
+all errors appear to involve one or more select's and one or more "depends on".

+
+Future kconfig work
+~~~~~~~~~~~~~~~~~~~
+
+Work on kconfig is welcomed on both areas of clarifying semantics and on
+evaluating the use of a full SAT solver for it. A full SAT solver can be
+desirable to enable more complex dependency mappings and / or queries,
+for instance on possible use case for a SAT solver could be that of handling
+the current known recursive dependency issues. It is not known if this would
+address such issues but such evaluation is desirable. If support for a full SAT
+solver proves too complex or that it cannot address recursive dependency issues
+Kconfig should have at least clear and well defined semantics which also
+addresses and documents limitations or requirements such as the ones dealing
+with recursive dependencies.
+
+Further work on both of these areas is welcomed on Kconfig. We elaborate
+on both of these in the next two subsections.
+
+Semantics of Kconfig
+~~~~~~~~~~~~~~~~~~~~
+
+The use of Kconfig is broad, Linux is now only one of Kconfig's users:
+one study has completed a broad analysis of Kconfig use in 12 projects [0]_.
+Despite its widespread use, and although this document does a reasonable job
+in documenting basic Kconfig syntax a more precise definition of Kconfig
+semantics is welcomed. One project deduced Kconfig semantics through
+the use of the xconfig configurator [1]_. Work should be done to confirm if
+the deduced semantics matches our intended Kconfig design goals.
+
+Having well defined semantics can be useful for tools for practical
+evaluation of depenencies, for instance one such use known case was work to
+express in boolean abstraction of the inferred semantics of Kconfig to
+translate Kconfig logic into boolean formulas and run a SAT solver on this to
+find dead code / features (always inactive), 114 dead features were found in
+Linux using this methodology [1]_ (Section 8: Threats to validity).
+
+Confirming this could prove useful as Kconfig stands as one of the the leading
+industrial variability modeling languages [1]_ [2]_. Its study would help
+evaluate practical uses of such languages, their use was only theoretical
+and real world requirements were not well understood. As it stands though
+only reverse engineering techniques have been used to deduce semantics from
+variability modeling languages such as Kconfig [3]_.

+.. [3] http://gsd.uwaterloo.ca/sites/default/files/icse2011.pdf
+
+Full SAT solver for Kconfig
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Although SAT solvers [4]_ haven't yet been used by Kconfig directly, as noted
+in the previous subsection, work has been done however to express in boolean
+abstraction the inferred semantics of Kconfig to translate Kconfig logic into
+boolean formulas and run a SAT solver on it [5]_. Another known related project
+is CADOS [6]_ (former VAMOS [7]_) and the tools, mainly undertaker [8]_, which
+has been introduced first with [9]_. The basic concept of undertaker is to
+exract variability models from Kconfig, and put them together with a
+propositional formula extracted from CPP #ifdefs and build-rules into a SAT
+solver in order to find dead code, dead files, and dead symbols. If using a SAT
+solver is desirable on Kconfig one approach would be to evaluate repurposing
+such efforts somehow on Kconfig. There is enough interest from mentors of
+existing projects to not only help advise how to integrate this work upstream
+but also help maintain it long term. Interested developers should visit:

-Introduction
-------------
-
-The configuration database is a collection of configuration options
-organized in a tree structure:
-
- +- Code maturity level options
- | +- Prompt for development and/or incomplete code/drivers
- +- General setup
- | +- Networking support
- | +- System V IPC
- | +- BSD Process Accounting
- | +- Sysctl support
- +- Loadable module support
- | +- Enable loadable module support
- | +- Set version information on all module symbols
- | +- Kernel module loader
- +- ...
-
-Every entry has its own dependencies. These dependencies are used
-to determine the visibility of an entry. Any child entry is only
-visible if its parent entry is also visible.
-
-Menu entries
-------------
-
-Most entries define a config option; all other entries help to organize
-them. A single configuration option is defined like this:
-
-config MODVERSIONS
- bool "Set version information on all module symbols"
- depends on MODULES
- help
- Usually, modules have to be recompiled whenever you switch to a new
- kernel. ...
-
-Every line starts with a key word and can be followed by multiple
-arguments. "config" starts a new config entry. The following lines
-define attributes for this config option. Attributes can be the type of
-the config option, input prompt, dependencies, help text and default
-values. A config option can be defined multiple times with the same
-name, but every definition can have only a single input prompt and the
-type must not conflict.
-
-Menu attributes
----------------
-
-A menu entry can have a number of attributes. Not all of them are
-applicable everywhere (see syntax).
-
-- type definition: "bool"/"tristate"/"string"/"hex"/"int"
- Every config option must have a type. There are only two basic types:
- tristate and string; the other types are based on these two. The type
- definition optionally accepts an input prompt, so these two examples
- are equivalent:
-
- bool "Networking support"
- and
- bool
- prompt "Networking support"
-
-- input prompt: "prompt" <prompt> ["if" <expr>]
- Every menu entry can have at most one prompt, which is used to display
- to the user. Optionally dependencies only for this prompt can be added
- with "if".
-
-- default value: "default" <expr> ["if" <expr>]
- A config option can have any number of default values. If multiple
- default values are visible, only the first defined one is active.
- Default values are not limited to the menu entry where they are
- defined. This means the default can be defined somewhere else or be
- overridden by an earlier definition.
- The default value is only assigned to the config symbol if no other
- value was set by the user (via the input prompt above). If an input
- prompt is visible the default value is presented to the user and can
- be overridden by him.
- Optionally, dependencies only for this default value can be added with
- "if".
-
-- type definition + default value:
- "def_bool"/"def_tristate" <expr> ["if" <expr>]
- This is a shorthand notation for a type definition plus a value.
- Optionally dependencies for this default value can be added with "if".
-
-- dependencies: "depends on" <expr>
- This defines a dependency for this menu entry. If multiple
- dependencies are defined, they are connected with '&&'. Dependencies
- are applied to all other options within this menu entry (which also
- accept an "if" expression), so these two examples are equivalent:
-
- bool "foo" if BAR
- default y if BAR
- and
- depends on BAR
- bool "foo"
- default y
-
-- reverse dependencies: "select" <symbol> ["if" <expr>]
- While normal dependencies reduce the upper limit of a symbol (see
- below), reverse dependencies can be used to force a lower limit of
- another symbol. The value of the current menu symbol is used as the
- minimal value <symbol> can be set to. If <symbol> is selected multiple
- times, the limit is set to the largest selection.
- Reverse dependencies can only be used with boolean or tristate
- symbols.
- Note:
- select should be used with care. select will force
- a symbol to a value without visiting the dependencies.
- By abusing select you are able to select a symbol FOO even
- if FOO depends on BAR that is not set.
- In general use select only for non-visible symbols
- (no prompts anywhere) and for symbols with no dependencies.
- That will limit the usefulness but on the other hand avoid
- the illegal configurations all over.
-
-- limiting menu display: "visible if" <expr>
- This attribute is only applicable to menu blocks, if the condition is
- false, the menu block is not displayed to the user (the symbols
- contained there can still be selected by other symbols, though). It is
- similar to a conditional "prompt" attribute for individual menu
- entries. Default value of "visible" is true.
-
-- numerical ranges: "range" <symbol> <symbol> ["if" <expr>]
- This allows to limit the range of possible input values for int
- and hex symbols. The user can only input a value which is larger than
- or equal to the first symbol and smaller than or equal to the second
- symbol.
-
-- help text: "help" or "---help---"
- This defines a help text. The end of the help text is determined by
- the indentation level, this means it ends at the first line which has
- a smaller indentation than the first line of the help text.
- "---help---" and "help" do not differ in behaviour, "---help---" is
- used to help visually separate configuration logic from help within
- the file as an aid to developers.
-
-- misc options: "option" <symbol>[=<value>]
- Various less common options can be defined via this option syntax,
- which can modify the behaviour of the menu entry and its config
- symbol. These options are currently possible:
-
- - "defconfig_list"
- This declares a list of default entries which can be used when
- looking for the default configuration (which is used when the main
- .config doesn't exists yet.)
-
- - "modules"
- This declares the symbol to be used as the MODULES symbol, which
- enables the third modular state for all config symbols.
- At most one symbol may have the "modules" option set.
-
- - "env"=<value>
- This imports the environment variable into Kconfig. It behaves like
- a default, except that the value comes from the environment, this
- also means that the behaviour when mixing it with normal defaults is
- undefined at this point. The symbol is currently not exported back
- to the build environment (if this is desired, it can be done via
- another symbol).
-
- - "allnoconfig_y"
- This declares the symbol as one that should have the value y when
- using "allnoconfig". Used for symbols that hide other symbols.
-
-Menu dependencies
------------------
-
-Dependencies define the visibility of a menu entry and can also reduce
-the input range of tristate symbols. The tristate logic used in the
-expressions uses one more state than normal boolean logic to express the
-module state. Dependency expressions have the following syntax:
-
-<expr> ::= <symbol> (1)
- <symbol> '=' <symbol> (2)
- <symbol> '!=' <symbol> (3)
- '(' <expr> ')' (4)
- '!' <expr> (5)
- <expr> '&&' <expr> (6)
- <expr> '||' <expr> (7)
-
-Expressions are listed in decreasing order of precedence.
-
-(1) Convert the symbol into an expression. Boolean and tristate symbols
- are simply converted into the respective expression values. All
- other symbol types result in 'n'.
-(2) If the values of both symbols are equal, it returns 'y',
- otherwise 'n'.
-(3) If the values of both symbols are equal, it returns 'n',
- otherwise 'y'.
-(4) Returns the value of the expression. Used to override precedence.
-(5) Returns the result of (2-/expr/).
-(6) Returns the result of min(/expr/, /expr/).
-(7) Returns the result of max(/expr/, /expr/).
-
-An expression can have a value of 'n', 'm' or 'y' (or 0, 1, 2
-respectively for calculations). A menu entry becomes visible when its
-expression evaluates to 'm' or 'y'.
-
-There are two types of symbols: constant and non-constant symbols.
-Non-constant symbols are the most common ones and are defined with the
-'config' statement. Non-constant symbols consist entirely of alphanumeric
-characters or underscores.
-Constant symbols are only part of expressions. Constant symbols are
-always surrounded by single or double quotes. Within the quote, any
-other character is allowed and the quotes can be escaped using '\'.
-
-Menu structure
---------------
-
-The position of a menu entry in the tree is determined in two ways. First
-it can be specified explicitly:
-
-menu "Network device support"
- depends on NET
-
-config NETDEVICES
- ...
-
-endmenu
-
-All entries within the "menu" ... "endmenu" block become a submenu of
-"Network device support". All subentries inherit the dependencies from
-the menu entry, e.g. this means the dependency "NET" is added to the
-dependency list of the config option NETDEVICES.
-
-The other way to generate the menu structure is done by analyzing the
-dependencies. If a menu entry somehow depends on the previous entry, it
-can be made a submenu of it. First, the previous (parent) symbol must
-be part of the dependency list and then one of these two conditions
-must be true:
-- the child entry must become invisible, if the parent is set to 'n'
-- the child entry must only be visible, if the parent is visible
-
-config MODULES
- bool "Enable loadable module support"
-
-config MODVERSIONS
- bool "Set version information on all module symbols"
- depends on MODULES
-
-comment "module support disabled"
- depends on !MODULES
-
-MODVERSIONS directly depends on MODULES, this means it's only visible if
-MODULES is different from 'n'. The comment on the other hand is always
-visible when MODULES is visible (the (empty) dependency of MODULES is
-also part of the comment dependencies).
-
-
-Kconfig syntax
---------------
-
-The configuration file describes a series of menu entries, where every
-line starts with a keyword (except help texts). The following keywords
-end a menu entry:
-- config
-- menuconfig
-- choice/endchoice
-- comment
-- menu/endmenu
-- if/endif
-- source
-The first five also start the definition of a menu entry.
-
-config:
-
- "config" <symbol>
- <config options>
-
-This defines a config symbol <symbol> and accepts any of above
-attributes as options.
-
-menuconfig:
- "menuconfig" <symbol>
- <config options>
-
-This is similar to the simple config entry above, but it also gives a
-hint to front ends, that all suboptions should be displayed as a
-separate list of options.
-
-choices:
-
- "choice" [symbol]
- <choice options>
- <choice block>
- "endchoice"
-
-This defines a choice group and accepts any of the above attributes as
-options. A choice can only be of type bool or tristate, while a boolean
-choice only allows a single config entry to be selected, a tristate
-choice also allows any number of config entries to be set to 'm'. This
-can be used if multiple drivers for a single hardware exists and only a
-single driver can be compiled/loaded into the kernel, but all drivers
-can be compiled as modules.
-A choice accepts another option "optional", which allows to set the
-choice to 'n' and no entry needs to be selected.
-If no [symbol] is associated with a choice, then you can not have multiple
-definitions of that choice. If a [symbol] is associated to the choice,
-then you may define the same choice (ie. with the same entries) in another
-place.
-
-comment:
-
- "comment" <prompt>
- <comment options>
-
-This defines a comment which is displayed to the user during the
-configuration process and is also echoed to the output files. The only
-possible options are dependencies.
-
-menu:
-
- "menu" <prompt>
- <menu options>
- <menu block>
- "endmenu"
-
-This defines a menu block, see "Menu structure" above for more
-information. The only possible options are dependencies and "visible"
-attributes.
-
-if:
-
- "if" <expr>
- <if block>
- "endif"
-
-This defines an if block. The dependency expression <expr> is appended
-to all enclosed menu entries.
-
-source:
-
- "source" <prompt>
-
-This reads the specified configuration file. This file is always parsed.
-
-mainmenu:

-Kconfig hints
--------------
-This is a collection of Kconfig tips, most of which aren't obvious at
-first glance and most of which have become idioms in several Kconfig
-files.
-
-Adding common features and make the usage configurable
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-It is a common idiom to implement a feature/functionality that are
-relevant for some architectures but not all.
-The recommended way to do so is to use a config variable named HAVE_*
-that is defined in a common Kconfig file and selected by the relevant
-architectures.
-An example is the generic IOMAP functionality.
-
-We would in lib/Kconfig see:
-
-# Generic IOMAP is used to ...
-config HAVE_GENERIC_IOMAP
-
-config GENERIC_IOMAP
- depends on HAVE_GENERIC_IOMAP && FOO
-
-And in lib/Makefile we would see:
-obj-$(CONFIG_GENERIC_IOMAP) += iomap.o
-
-For each architecture using the generic IOMAP functionality we would see:
-
-config X86
- select ...
- select HAVE_GENERIC_IOMAP
- select ...
-
-Note: we use the existing config option and avoid creating a new
-config variable to select HAVE_GENERIC_IOMAP.
-
-Note: the use of the internal config variable HAVE_GENERIC_IOMAP, it is
-introduced to overcome the limitation of select which will force a
-config option to 'y' no matter the dependencies.
-The dependencies are moved to the symbol GENERIC_IOMAP and we avoid the
-situation where select forces a symbol equals to 'y'.
-
-Build as module only
-~~~~~~~~~~~~~~~~~~~~
-To restrict a component build to module-only, qualify its config symbol
-with "depends on m". E.g.:
-
-config FOO
- depends on BAR && m
-
-limits FOO to module (=m) or disabled (=n).

+======================
+Kconfig macro language
+======================
+
+Concept
+-------
+
+The basic idea was inspired by Make. When we look at Make, we notice sort of
+two languages in one. One language describes dependency graphs consisting of
+targets and prerequisites. The other is a macro language for performing textual
+substitution.
+
+There is clear distinction between the two language stages. For example, you
+can write a makefile like follows::
+
+ APP := foo
+ SRC := foo.c
+ CC := gcc
+
+ $(APP): $(SRC)
+ $(CC) -o $(APP) $(SRC)
+
+The macro language replaces the variable references with their expanded form,
+and handles as if the source file were input like follows::
+
+ foo: foo.c
+ gcc -o foo foo.c
+
+Then, Make analyzes the dependency graph and determines the targets to be
+updated.
+
+The idea is quite similar in Kconfig - it is possible to describe a Kconfig
+file like this::
+
+ CC := gcc
+
+ config CC_HAS_FOO
+ def_bool $(shell, $(srctree)/scripts/gcc-check-foo.sh $(CC))
+
+The macro language in Kconfig processes the source file into the following
+intermediate::
+
+ config CC_HAS_FOO
+ def_bool y
+
+Then, Kconfig moves onto the evaluation stage to resolve inter-symbol
+dependency as explained in kconfig-language.txt.
+
+
+Variables
+---------
+
+Like in Make, a variable in Kconfig works as a macro variable. A macro
+variable is expanded "in place" to yield a text string that may then be
+expanded further. To get the value of a variable, enclose the variable name in
+$( ). The parentheses are required even for single-letter variable names; $X is
+a syntax error. The curly brace form as in ${CC} is not supported either.
+
+There are two types of variables: simply expanded variables and recursively
+expanded variables.
+
+A simply expanded variable is defined using the := assignment operator. Its
+righthand side is expanded immediately upon reading the line from the Kconfig
+file.
+
+A recursively expanded variable is defined using the = assignment operator.
+Its righthand side is simply stored as the value of the variable without
+expanding it in any way. Instead, the expansion is performed when the variable
+is used.
+
+There is another type of assignment operator; += is used to append text to a
+variable. The righthand side of += is expanded immediately if the lefthand
+side was originally defined as a simple variable. Otherwise, its evaluation is
+deferred.
+
+The variable reference can take parameters, in the following form::
+
+ $(name,arg1,arg2,arg3)
+
+You can consider the parameterized reference as a function. (more precisely,
+"user-defined function" in contrast to "built-in function" listed below).
+
+Useful functions must be expanded when they are used since the same function is
+expanded differently if different parameters are passed. Hence, a user-defined
+function is defined using the = assignment operator. The parameters are
+referenced within the body definition with $(1), $(2), etc.
+
+In fact, recursively expanded variables and user-defined functions are the same
+internally. (In other words, "variable" is "function with zero argument".)
+When we say "variable" in a broad sense, it includes "user-defined function".
+
+
+Built-in functions
+------------------
+
+Like Make, Kconfig provides several built-in functions. Every function takes a
+particular number of arguments.
+
+In Make, every built-in function takes at least one argument. Kconfig allows
+zero argument for built-in functions, such as $(fileno), $(lineno). You could
+consider those as "built-in variable", but it is just a matter of how we call
+it after all. Let's say "built-in function" here to refer to natively supported
+functionality.
+
+Kconfig currently supports the following built-in functions.
+
+ - $(shell,command)
+
+ The "shell" function accepts a single argument that is expanded and passed
+ to a subshell for execution. The standard output of the command is then read
+ and returned as the value of the function. Every newline in the output is
+ replaced with a space. Any trailing newlines are deleted. The standard error
+ is not returned, nor is any program exit status.
+
+ - $(info,text)
+
+ The "info" function takes a single argument and prints it to stdout.
+ It evaluates to an empty string.
+
+ - $(warning-if,condition,text)
+
+ The "warning-if" function takes two arguments. If the condition part is "y",
+ the text part is sent to stderr. The text is prefixed with the name of the
+ current Kconfig file and the current line number.
+
+ - $(error-if,condition,text)
+
+ The "error-if" function is similar to "warning-if", but it terminates the
+ parsing immediately if the condition part is "y".
+
+ - $(filename)
+
+ The 'filename' takes no argument, and $(filename) is expanded to the file
+ name being parsed.
+
+ - $(lineno)
+
+ The 'lineno' takes no argument, and $(lineno) is expanded to the line number
+ being parsed.
+
+
+Make vs Kconfig
+---------------
+
+Kconfig adopts Make-like macro language, but the function call syntax is
+slightly different.
+
+A function call in Make looks like this::
+
+ $(func-name arg1,arg2,arg3)
+
+The function name and the first argument are separated by at least one
+whitespace. Then, leading whitespaces are trimmed from the first argument,
+while whitespaces in the other arguments are kept. You need to use a kind of
+trick to start the first parameter with spaces. For example, if you want
+to make "info" function print " hello", you can write like follows::
+
+ empty :=
+ space := $(empty) $(empty)
+ $(info $(space)$(space)hello)
+
+Kconfig uses only commas for delimiters, and keeps all whitespaces in the
+function call. Some people prefer putting a space after each comma delimiter::
+
+ $(func-name, arg1, arg2, arg3)
+
+In this case, "func-name" will receive " arg1", " arg2", " arg3". The presence
+of leading spaces may matter depending on the function. The same applies to
+Make - for example, $(subst .c, .o, $(sources)) is a typical mistake; it
+replaces ".c" with " .o".
+
+In Make, a user-defined function is referenced by using a built-in function,
+'call', like this::
+
+ $(call my-func,arg1,arg2,arg3)
+
+Kconfig invokes user-defined functions and built-in functions in the same way.
+The omission of 'call' makes the syntax shorter.
+
+In Make, some functions treat commas verbatim instead of argument separators.
+For example, $(shell echo hello, world) runs the command "echo hello, world".
+Likewise, $(info hello, world) prints "hello, world" to stdout. You could say
+this is _useful_ inconsistency.
+
+In Kconfig, for simpler implementation and grammatical consistency, commas that
+appear in the $( ) context are always delimiters. It means::
+
+ $(shell, echo hello, world)
+
+is an error because it is passing two parameters where the 'shell' function
+accepts only one. To pass commas in arguments, you can use the following trick::
+
+ comma := ,
+ $(shell, echo hello$(comma) world)
+
+
+Caveats
+-------
+
+A variable (or function) cannot be expanded across tokens. So, you cannot use
+a variable as a shorthand for an expression that consists of multiple tokens.
+The following works::
+
+ RANGE_MIN := 1
+ RANGE_MAX := 3
+
+ config FOO
+ int "foo"
+ range $(RANGE_MIN) $(RANGE_MAX)
+
+But, the following does not work::
+
+ RANGES := 1 3
+
+ config FOO
+ int "foo"
+ range $(RANGES)
+
+A variable cannot be expanded to any keyword in Kconfig. The following does
+not work::
+
+ MY_TYPE := tristate
+
+ config FOO
+ $(MY_TYPE) "foo"
+ default y
+
+Obviously from the design, $(shell command) is expanded in the textual
+substitution phase. You cannot pass symbols to the 'shell' function.
+
+The following does not work as expected::
+
+ config ENDIAN_FLAG
+ string
+ default "-mbig-endian" if CPU_BIG_ENDIAN
+ default "-mlittle-endian" if CPU_LITTLE_ENDIAN
+
+ config CC_HAS_ENDIAN_FLAG
+ def_bool $(shell $(srctree)/scripts/gcc-check-flag ENDIAN_FLAG)
+
+Instead, you can do like follows so that any function call is statically
+expanded::
+
+ config CC_HAS_ENDIAN_FLAG
+ bool
+ default $(shell $(srctree)/scripts/gcc-check-flag -mbig-endian) if CPU_BIG_ENDIAN
+ default $(shell $(srctree)/scripts/gcc-check-flag -mlittle-endian) if CPU_LITTLE_ENDIAN

+The behavior of 'y' choice is intuitive. If choice values are tristate,
+the choice can be 'm' where each value can be enabled independently.
+Also, if a choice is marked as 'optional', the whole choice can be
+invisible.

- detecting the absence of a lookahead is sufficient to determine
- that there is no unexpected or expected token to report. In that
- case, just report a simple "syntax error".
- - Don't assume there isn't a lookahead just because this state is a
- consistent state with a default action. There might have been a
- previous inconsistent state, consistent state with a non-default
- action, or user semantic action that manipulated yychar.
- - Of course, the expected token list depends on states to have
- correct lookahead information, and it depends on the parser not
- to perform extra reductions after fetching a lookahead from the
- scanner and before detecting a syntax error. Thus, state merging
- (from LALR or IELR) and default reductions corrupt the expected

- one exception: it will still contain any token that will not be
